METHOD vOF AND .VA'EPARATUSl FOR FORMING ARTICLES.

.Applicationv filed November 30, 1923. Serial No. 677,719.

My invention relates to a method of and apparatus 'for forming articles from parchment and the like, and more particularly `to method ot and apparatus for forming articles of the character described from sheets ot such material.

v Theinvention has among its objects the production of a device ot the kind described and method and apparatus torinakinn' the same,which will be simple, inexpensive, durable, reliable1 satisfactory and efiicieut for use wherever found applicable.

vMany other object-s and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. A f

In the drawings, whereindike reference characters indicate like or corresponding parts:`

Fig. l0 is sectional view of a portion of a modilied shade; 1 Y K f" Fig. 1l is a-,reduced top plan view of the same and y Fie'. l2 is aftragmentary sectional viewy illustrating; another type.

ln the C rawings, l fndicates a sheet ot inaterial, such as papcr,`iibre-board, parchment, or the like, from which a blank 2 is to be cut in the desired size and shape. `This blank Yin the form shown in l-e, inclusive, ior making a tapered shade, is substantially l arcuate Valong its top and the bottoni bound-v ing edges, the end edges being,` straight and convergent. A scored line 3 may be formed on the blank parallel to the top arcuate edge and adjacent thereto, the distance between said arcuate.r edgeand line 3 determining the width of the flange t which is to .be formed on the shade. After the blank has been cut from the sheet, it is then preferably decorated or ornaine'nted in any desired manner, as indicated `atl 5. l i l Y 1 4 The next stepin forming,` the shade is vto fold the top edge inwardly along the score-d line, as shown lin Fig, 3, to forni the inwardly and downwardly directed flange 4. Ad-

hesive is then applied to one or both of the end edges of theshade and these end yedges are `overlapped and secured, the shade beingv socket formed in the central top part of the member' 6. y l

A metallic outer ring or sleeve 8, also tapered so as to conform to the shape of the shade and cooperate with the part 6, isypro- 4vided and after the adhesive'has kbeen "applied, as previously mentioned, with the ends the Vshade overlapped, and they shade slipped over the part 6, the sleeve 8 is'dropped `to encircle-the shade, thus holding it securely 1n place int-he setting' mold, the 'flange lyingv in the socket portion. y

A ram 9 preferably of metal, with a. heatinsulated handle lO, is adapted to be pressed into the socket portion or the mold to hold hea-ted by any a burner ll arranged'tlierebelow. A bracket l2 may be employed to hold the mold a suitable distancefr'om therrburner. rllhe shade is held in the mold a sufficient length of time to enable Vthe adhesive to completely dry aiterwhich the Vram and outer sleeve are removed and the `shade takencitl the part'i.

lt is to be noted at this point that with the flange 4 extends inwardly and downwardly :trcmlthe top ot the shade at such an angle that the line bisecting the angle between the flan-ge and outer wall is parallel to the longithe flanger lof the shade between the ram l 1 and-mold.l rThe entire mold is warmed` or suitable means, astor instance,

. type ot shade illustrated in Figs. tand 5,'thev Vtudinal or rotational axis ofthe shade. After taking the shade from the setting mold, it is placed in anembossing or beading moldas shown in Figs. 8 and 9, wherein the lower ori large end is outwardly beaded, as at 13.

The embossing "mold shown comprises a chambered part 14 having its inner Wall shaped to smoothly engage the outer periphery of the shade but being slightly shorter than the shade so that the shade will project therebeyond a suitable distance. An inner sleeve' 15 is removably positioned within the shade after it has been placed in the mold, this sleeve being of substantially the same length as the part 14.

A ring member, made in'one `or more sections, there being two parts shown as at 16 and 16', isarranged to encircle the projecting portion of the shade, said ring member. having an annular groove provided therein and into which the proj ecting-portion of the shade is pressed or rolled.

`1923. v i Y In the form shown in Fig. 7, theshade does `not have tapered sides, but is straight. It is therefore necessary to crinkle the flange asY `at 26 so that it will project inwardly and The parts 16 and 16 are pivotally mounted upon an upright part 17 and have projecting handle portions 18, whereby they may be swung into or out of operativeposition and held in place during the embossing.

A roller 19 having a convex peripheral edge Vton cooperate with the annular groove in the tated so that the roller 19 engages the inner periphery of the projecting portion of the shade and expands or bulges it radially outwardly into the groove formed in' the rin 16-16. This is suicientito shape the shade at that end and form a bead thereat. The shade may then be removed from the mechanism andV treated in any suitable manner, dependent upon the purpose for which it is to be used. For example, the sha-de may be` treated with applications of oil in a suitable manner so as to render portions of it opaque and other portions translucent, whereby the .shade, evcnthough it is made of paper, will to all intents and purposes appear as if it `fwere made of parchment.

v This method of treating paper stock has been fully set forth in my Patent No. 1,471,021 issued October 16,

downwardly of the top edge of the shade. This crinkling may be effected when blanking out as shown in Fig. 1;,"or at such time. Y

and with such apparatus as may be desired. A slightly different construction is shown in Fig. 10', in which 30 represents the wall or body of the shade which is shown covered shade. In this case, a top part 36, which also Y may becovered as indicated atl 38, is shown turned down and secured to side wall, forexample, adjacent the top. For ventilation, openings 39 are shown, as will be seen by reference to Fig. 11. This shade otherwise is made substantially the same asthe other one described both as to shape, ornamenting and treating.

It is adapted to be supported on alamp' `or fixture at the opening 40. The figure shows the parts enlarged injorder that the details ma be apparent. It has been found that the bo y 30 when covered, as indicated, may be satisfactorily treated without injuring the i shade. 1

In the form shown in Fig.12, 41 represents the shade, 42 a cross partition'similar to 36, which in this instance is arranged adjacent the bottom, which mayv of course, be con' i structed similar to that shown in Fior. 10' or Vthe other figures. This t peis particularly adapted for use oncandlle-type fixtures. I have notconsidered it necessary to illustrate the various types of fittings which may be used. Such additional trimmings may be attached as found desirable. f f

Either of the shades shown may be applied y upon a bracket carried by the fixture or the bulb, or various other methods may be employedv to support the same. The shades may be quickly and easily manufactured and aty A low cost.V

Having thus describedjmy invention, vit is Y obvious that various Vimmaterial modications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrange,

ment and combination ofy parts herein shown and described,.or uses mentioned.

What I claim as new and desireito secure by Letters Patent is:

1. Inapparatus for forming articles from parchmentized material, paper and the like, a mold comprising an inner member around which a sheet of such material may be wound,

said inner member havinga depression in its top, a tubular shell adapted to surroundv saidy liao ' tubular member around which a sheet of material is wound, a transverse wall within said member intermediate its ends forming a depression in the top of said member having inwardly inclined walls, a tubular shell to 3U Surround said inner member and adapted to seat on the material around said member, a plug removably litted into said depression to clamp a portion of the sheet between said plug andthe surrounding wall of the depression, and means for heating said inner meme ber.

In testimony whereof, I signed my name.
